' NEW YORK, N. Y., A CORPORATION OF DELAWARE SPRING BED BOTTOM Application filed February 23, 1928. Serial no. sesame.

This invention has relation to that class of spring bed bottoms (which term as herein used is intended to include lounges, spring seats, and the like, in which vertically disposed coil springs are employed; and the invention is designed to provide improved means for connecting the coil springs together'in such manner as to insure against their distortion and displacement in use.

' IO'The invention. consists in the features of noveltyhereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claims at the end of this specificati on.

Figure 1 is a plan View showing portions of a spring bed bottom embodying my invention. v

Figure Q is a view in side elevation.

Figure 3 is a detail perspective View showing the manner in which the tie-wires and key-wires are united together and to the coil springs. I

i The coil springs 1, which may be of any usual or suitable form, will be arranged in parallel rows extending longitudinally and transversely of the bed bottom. The top convolutions ofthese springs may be connected in the usual manner by helical springs 2, and the lower ends of the springs 1 may be mounted upon supporting bars 3 to which they will be secured by loop wires 4, in manner well understood in the art.

From the springs 1, at a suitable point thereon and preferably about centrally of the springs, extend continuous tie-wires 5 that are formed with spring-engaging loops 6. As shown, the tie-wires 5 pass along one side of and preferably beneath one of the convolutions l of the springs 1, while the adjacent loop 6 of the tie-wire 5 extends across and partially around said convolution.

The tire-wires 5 engage the continuous key-wires 7 that are interlocked with the tiewires and preferably with the loop 6 of said wires, In the preferred embodiment of my invention, each key-wire 7 is formed with straight offset portions between which are made S-shaped bends to produce the laterally oiiset loops 7 a and 7 In making my improved bed bottom, the

springs 1 may be assembled in parallel rows, their lower ends being mounted upon the supporting bars 3 that are connected by the loop wires 4 in the usual manner, and the upper ends of the springs 1 may be united in the usual way, as for example, by helical springs 2 engaging their top eonvolutions.

A tie-wire 5 will be engaged with each of the coil springs of a row, preferably by passing such tie-wire beneath one of the convolutions of each spring, after which each loop 6 of the tie-wire 5 will be brought across and partially around said convolution, as clearly shown in Figs. 2 and 3 of the drawings. lVhen the tie-wires have thus been positioned with respect to the coil springs 1, each keywire will be inserted transversely of the tiewires and through the rows of springs 1 in such manner that each loop or bend 7" of the key-wires 7 shall pass through the companion loop 6 of the tiewire 5 and thus securely retain the tie-wire in engagement with the corresponding coil spring and prevent any movement of the spring in the direction of the length of the tie-wire. WVhen the loop 7 of the key-wire 7 is thus passed through the loop 6 of the tie-wire 5, the loop 7 of the keywire 7 will engage one of the arms of the tiewire loop 6, as shown in Fig. 3 of the drawings. With the parts thus assembled, the

loops 7 and 7 will be compressed or closed sufiiciently, as shown in Fig. 1 of the drawings, to cause the loop 7* to be retained in interlocked engagement with the loop 6 of the tie-wire 5. \Vhcn the key-wires 7 have been thus placed, they will effectively serve to prevent any movement or distortion of the tion may be employed without its adoption as an entirety.

I claim as my invention:

1. A spring bed comprising the combina tion of coil springs, of tie wires, the bodies of which pass on one side of aconvolution of,

- each spring and are formed with loops which extend through a convolution and are bent at anacute angle around the opposite side thereof, and key wires extending transversely of said tie wires, said key wires having bent portions interlocking with and substantially enclosing'parts of said wire loops, each of related to a single coil'spring.

said loops being operlatively related to a sin;

'gle coil spring. i 2. A spring-bed comprising the combrnation of coil springs,-o-f tie wires, the bodies of which passion one s deof a convolut on of each spring and are formed wlth loops which extend through; a convolution and are bent .at an acute angle around the opposite side thereof, an 01 key wires extending transversely of said tic wir es, said key wires having 8- .shaped bent portions interlocking with and substantially enclosing parts of said wire said convolution partially around the same,

and key wiresextending transversely of said t e, wires, said key wires having ofiset .por-

tionswith reverse bends between said offset portions to engage the tie wire loops, eachpf said loops beingoperatively related tota S1117 gle coil spring. I V a 4. A. springbed bottom comprising the combinationof coil springs, of tie wires, the bodies whereof pass on one side of a convovolution, each key wire having its main portion arranged on the same side of said convolution as the main portion of the tie wire and having an S-shaped bend therein, one of the bends of said 8 projecting through the tie m extending through'acoil of each spring, and j a plurality of key wires extending transverselyof said tie wires,-each key wire having o-fi'- set bends forming sockets receiving and interlocking with said loops and clamping said tie wires to said coil spr1ngs, said tie wires loops projecting from said springsso that the offset bendsof said key wires may readily be assembled into interlocking relation therewithiby a simple movement of said key wires.
